So Hinton doesn't trust the tech leaders but then the consequence of having governments censor LLMs is that only tech leaders and governments have unlimited access to AI.
If someone manages with the help of AI to hack into a vital system, then the system was already in a critically bad state beforehand. If developers can't use AI to check the code for security flaws, then security gets worse and not better.
I would posit that systems being hacked by AI were already vulnerable to the huge caches of secret zero days held by intelligence agencies and organized crime around the world. Which we know exist.
Insecure is insecure. These systems never were secure.
